When we rub glass rod with fur, the glass rod will acquire

A Positive charge
B Negative charge

what can be the answer?

The options given here are a plastic scale,a woollen cloth, an inflated balloon and a COPPER rod, not a GLASS rod. How can the options appear differently for others, since many people here are saying that there is glass rod involved? Also, plastic is an insulator of electricity, so ideally it wouldn't acquire any charge, right? SOF should give a solution to this problem.

When rubbed with fur, glass will become negatively charged. However if silk is used instead of fur, glass will acquire a positive charge.
